Practice With Monohybrid Punnett Squares Answer Key Pdf
Genetics is the study of heredity and how traits are passed from one generation to the next. Punnett squares are a useful tool in genetics that can help predict the probability of traits being passed on. In this article, we will be discussing monohybrid Punnett squares and providing an answer key PDF for those looking to practice.
What is a Monohybrid Punnett Square?
A monohybrid Punnett square is a tool used to predict the probability of offspring inheriting a certain trait from their parents. It is called monohybrid because it focuses on only one trait at a time. The square is made up of four boxes, with each box representing a possible combination of alleles from the parents.
How to Use a Monohybrid Punnett Square
To use a monohybrid Punnett square, you first need to determine the genotypes of the parents. This can be done by using the letters that represent the alleles for the trait. For example, let\’s say we are looking at the trait of flower color in pea plants. The dominant allele for purple flowers is represented by the letter P, and the recessive allele for white flowers is represented by the letter p. If one parent has the genotype PP (meaning they have two dominant alleles) and the other parent has the genotype pp (meaning they have two recessive alleles), the Punnett square would look like this:
| P | P |
| p | p |
The letters outside the box represent the alleles from each parent. The letters inside the box represent the possible genotypes of the offspring. In this case, all of the offspring would have the genotype Pp, meaning they would have one dominant allele and one recessive allele.
